- Information
High transparency: The film has high transparency and can clearly display the items in the package. For pharmaceutical packaging, it allows users to intuitively see the appearance, shape, color, etc. of the medicine, which is convenient for confirming the type and state of the medicine.
A certain barrier property: Although the barrier property of PVC film is not as good as that of aluminum foil, it can play a certain role in blocking oxygen, moisture and light as the inner film in cold double aluminum packaging, in combination with the outer layer of aluminum foil, etc., which helps to protect the quality and stability of the contents such as medicines.
Good heat sealing performance: It can be sealed and combined with cold aluminum or other materials through the heat sealing process to form a good sealed package, ensuring that the items in the package are not affected by the external environment and preventing the medicines from getting damp and deteriorating, etc.
Production process
PVC film is usually made of polyvinyl chloride resin and other modifiers through calendering or blow molding. When producing 6-filament transparent PVC film for cold double aluminum, it is necessary to strictly control various parameters in the production process, such as temperature, pressure, speed, etc., to ensure the uniformity of film thickness and performance stability. At the same time, in order to meet the special requirements of cold double aluminum packaging, it may be necessary to perform some special treatments on the PVC film, such as surface corona treatment, to improve its bonding performance with other materials.
Application field
It is mainly used in the field of pharmaceutical packaging, for cold double aluminum blister packaging of medicines. For example, the packaging of medicines such as tablets and capsules can provide good protection for medicines, extend the shelf life of medicines, and also facilitate the use and carrying of medicines. In addition, this 6-filament transparent PVC film may also be used in the packaging of some health products, small electronic components, etc. in combination with cold double aluminum for packaging.
Quality Standards
Thickness Standards: The thickness of 6-filament transparent PVC film is generally required to be strict, 6-filament is 0.06mm, and a certain tolerance range is allowed, but the deviation cannot be too large to ensure the performance of the film and the packaging effect.
Physical properties: Including indicators such as tensile strength and elongation at break, which need to meet certain standards to ensure that the film will not easily break or be damaged during the packaging process and transportation, storage and other links.
Chemical stability: PVC film should have good chemical stability and cannot react chemically with drugs and other substances in the package to avoid affecting the quality and safety of the drugs.
Sanitary standards: In pharmaceutical packaging applications, relevant hygiene standards and regulatory requirements for pharmaceutical packaging materials must be met to ensure that the film itself does not contain substances harmful to the human body, such as heavy metals, residual solvents, etc.
